DRIVING WITH THE ZF HP/VOITH<br />
DIWA.3 AUTOMATIC GEARBOX<br />
The ZF automatic gearbox has 4 or 5<br />
forward speeds and 1 reverse gear. The<br />
Voith automatic gearbox has 3 or 4 forward<br />
speeds and 1 reverse speed.<br />
These gearboxes also have a built-in retarder.<br />
The automatic gearbox is electrically<br />
operated by selecting the required gear from<br />
a row of gear selector buttons on the instrument<br />
panel.<br />
Depending upon the specific application of<br />
the vehicle, the automatic gearbox offers the<br />
following gear selector positions:<br />
- 3 positions: DNR<br />
- 6 positions: 123 DNR<br />
Gear selector positions:<br />
R - Reverse:<br />
Reverse gear may only be engaged whilst<br />
the vehicle is stationary and the engine is<br />
idling. To engage position “R” from position<br />
“D”, “1,2,3”, the brake pedal must be<br />
depressed.<br />
Never engage reverse gear whilst driving<br />
forward.<br />
The reversing lamps light up whilst in the<br />
“R” position with the contact switched on.<br />
N - neutral (stationary) position:<br />
Only engage the neutral position when the<br />
speed of the vehicle is less than 5 km/h or<br />
when the vehicle is stationary.<br />
D - normal position whilst driving<br />
forwards.<br />
In this position the gearbox automatically<br />
changes UP and DOWN through all the<br />
forward speeds (depending upon the road<br />
speed and the position of the accelerator<br />
pedal).<br />
Under certain circumstances during driving<br />
it is better to temporarily engage one of the<br />
options described below.<br />
1 - position for steep mountainous routes:<br />
This option is recommended for extreme<br />
height differences and steep inclines.<br />
The vehicle only drives in 1st gear. 2nd and<br />
3rd gear remain blocked. The maximum<br />
engine operation is reached due to this.<br />
The speed regulating system cannot be<br />
used whilst in position 1.<br />
2 - position for mountainous routes:<br />
This option is intended for long inclines and<br />
routes with steep hills.<br />
1st and 2nd gears are changed up and down<br />
depending on the engine load and the<br />
driving speed. 3rd and 4th gears remain<br />
blocked. The engine brake operation is<br />
further increased due to this.<br />
